Exterior Insulation Finish System or EIFS, also known as Synthetic Stucco, is a multi-layered finish that has been used on commercial buildings and residential houses in the United States for over 30 years. They provide superior energy efficiency and offer much greater design flexibility than other similar products. There are 3 layers to EIFS, the Inner, Middle, and Exterior layers. The Inner layer is made up of Expanded Polystyrene (EPS) board that is secured to the wall surface with an adhesive. The Middle Layer consists of the strong water-resistant base coat that is applied to the other side of the Expanded Polystyrene (EPS) board, and is strengthened by fiberglass mesh to increase durability. Lastly, the Exterior layer is a textured finish coat that is crack-resistant.
Expanded Polystyrene (EPS) for the EIFS system is a 2′ x 4′ polystyrene board with a thickness that ranges from 3/4′ – 4′ typically. The weight of the board is 1lb density and comes bundled accordingly to achieve a certain square footage.
